The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory

6. What do you think is the biggest problem facing the world today? I would say greed and ignorance is the biggest problem facing the world today. It is an aspect of human nature and seemingly intractable. I don’t expect the mass of humanity to undergo spiritual transformation to amend these aspects. However I do think that in order for problems to be solved such as objective conditions e.g. war and poverty‚ there has to be a change in social ethos- that of which is generally considered desirable
